When I install Windoes Media for my movies 4, the enable DVD checked box in programs (above Autorun) becomes unchecked. If I uninstall WM Movies4 , the disk drive reads dvd bluray ok. I still do not get the pop up scanning DVD screen that i used to get. How can I fix this? Windows 8 64bit, Arc Soft theatre 5, Windows media 4 are the programs I am using-so somehow WM for My movies 4 is the culprit-What to do?
